Application filed To all whom it mar/y concern:

Be it known that I, WILLIE Snow, a citizen of the United States,residing at Devils Lake, in the county of Ramsey and State of NorthDakota, have invented new and useful Improvements in Hand-Stamps, ofwhich the following is a specification.

Hand stamps for canceling postage stamps and for marking generally havea rigid connection between the handle and the die, hence when using thesame the matter to be printed does not show to advantage because ofunequal distribution of the pressure.

The purpose of the present invention is to equalize the pressure appliedwhen using the stamp so as to insure a plain impression being made sinceevery part of the die receives an equal pressure.

The invention provides a novel connection between the die and handle,whereby the die is at all times held in operative position and provisionhad for adapting the same to the surface so as to equalize the pressureand insure a plain impression, which is highly essential.

The invention consists of the novel features, details of constructionand combination of parts, which hereinafter will be more particularlyset forth, illustrated in the accompanying drawings, and pointed out inthe appended claims.

Referring to the drawings, forming a part of the specification, Figure 1is a vertical central section of a hand stamp embodying the invention.Fi 2 is a horizontal section on the line 5-5 0 Fig. 1. Fig. 3 is a Viewof the stamp inverted. Fig. 4 is a perspective view of the member of theconnection between the die and handle provided with the ball.

Corresponding and like parts are referred to in the followingdescription, and indicated in all the views of the drawings, by the samereference characters.

The hand stamp comprises a die 1, which is oblong, although it may be ofany shape and construction according to the matter to be printed. Thehandle 2 may be of any construction and is of approximately sphericalform to be conveniently grasped in the hand.

The connecting means between the handle and die are such as to admit ofsaid parts having a relative movement, whereby the printing surface ofthe die may receive a speclficationof [Letters Patent.

uniform pressure throughout its length and move to adapt itself to therelative position of the surface to receive the imprint. The connectingmeans comprises a rod 3, a clamp 4, and a stem 5 having a ball 6. Thestem 5 is threaded into the die 1 at a central point or may be securedthereto in any manner. The ball 6 at the upper end of the stem 5 has acircumferential groove 7 which receives jaws 8 at the lower ends of themembers of the clamp 4. The clamp 4.- is elongated and comprises similarmembers or sections, which are held together when the clamp is insertedin an opening 9 formed in the shank of the handle 2. When the members ofthe clamp 4 are brought together the jaws 8 fit within the groove 7 ofthe ball G and embrace opposite sides of the ball, thereby gripping thesame while admitting of a limited play between the clamp and stem, whichis essential to allow for relative movement between the die 1 and handle2 to attain the objects herein stated. A threaded opening 10 is formedin the upper end of the clamp 4 and receives the lower threaded end ofthe connecting rod 3. The connecting rod passes through an opening 11formed axially of the handle and in line with the opening 9. The upperend of the connecting rod is enlarged to form a head 12, which has agroove to receive the point of a screw driver or like tool, whereby theconnecting rod may be screwed into or out of the threaded opening 10. Ahelical spring 13 is interposed between the lower end of the handle 2and the die 1 and holds said parts in given position. Caps 14 are fittedto the lower end of the handle 2 and the upper side of the die 1. andreceive the ends of the helical spring 13, whereby the latter isretained in proper position. The caps 14: are centrally apertured toreceive the clamp 4 and the stem 5.

When the parts of the stamp are assem bled the helical spring 13 issubjected to pressure, whereb Y a tension thereon is created, saidsaring serving to hold the die 1 and the handle 2 in given position and.admitting of the .die having relative movement when the stamp is inoperation, so that the pressure exerted may be evenl distributedthroughout the printing sur ace of the die to the end that a plainimpression mt? be obtained.

*rom the foregoing description, taken in connection with theaccompanying drawings, the advanta es of the construction and of themethod 0 operation will be readily apparent to those skilled in the artto which the invention appertains, and while I have described theprinciple of operation of the invention, together with the device whichI now consider to be the embodiment thereof, I desire to have itunderstood that the device shown is merely illustrative, and that suchchanges may be made when desired as are within the scope of the claimsappended hereto.

Having thus described the invention what is claimed as new, is

l. A hand stamp comprisin a die, a handle having an axial opening tIierein, a stem secured to the die and provided at its upper end with aball, a sectional clamp havin jaws embracin opposite sides of the bal,the sections 0 said clamp being held together by the walls of theopening formed in the handle into which the said clamp is inserted, anda connecting rod for securing the clamp to the handle.

2. A hand stamp comprising a die, a handle having an axial opening, astem having one end attached to the die and provided at its opposite endwith a ball, a sectional clamp formed with jaws embracing o posite sidesof the ball and held together y the walls of the opening formed in saidhandle after the clamp has been inserted therein, said clamp having athreaded opening in its upper end, and a connecting rod having its lowerend threaded to engage the threaded end of the clamp and hold the partsin proper position.

3. A hand stamp comprising a die, a bandle having an opening formedcentrally therethrough, a stem secured to the die and provided at itsupper end with a ball in which a circumferential groove is formed, aclamp comprising similar sections having jaws at their lower ends toenter the groove of the ball and embrace opposite sides of the latter,said clamp having a threaded opening at its upper end and inserted inthe opening of the handle and having its sections se cured thereby, aconnecting rod inserted in the opening of the handle and having screwthread connection with the crank, and a helical spring inserted betweenthe handle and die.

In testimon 1 whereof I afiix my signature in presence 0" two witnesses.
